About SmartTier for Oracle with InfoScale™ product components in the VMware guest
SmartTier is a VxFS feature that enables you to allocate file storage space from different storage tiers according to rules you create. SmartTier provides a more flexible alternative compared to current approaches for tiered storage.
In an Oracle database environment, the access age rule can be applied to archivelog files and Flashback files. Oracle updates the header of each datafile at every database checkpoint and hence access age rules cannot be used for datafiles. For a partitioned table, we can use the name base rule to relocate files belonging to a given partition, for instance last year, to the secondary storage tier. However if a database does not have partitioned tables, current methods for relocation do not fit to the Oracle database environment.
To adopt a successful SmartTier policy and save storage costs, a method is needed for relocating Oracle objects which are accessed infrequently to the secondary tier. Relocating the entire file is not useful in all cases.
SmartTier for Oracle in the VMware environment works the same as in the physical environment.
